Yes Ford did, with an RFID chip hidden in the key. If you check the police records, you'll find that the Ford Focus is not stolen often, and I bet if you research the ones that are stolen- those are stolen with the keys.

If you really feel like you should do this, I wouldn't do it off the ignition, I'd do it off the clutch position switch or the neutral safety switch if you have an AT. Both of these will prevent the starter relay from energizing.

^^^ What he said. The difficult thing is unless you take good care and time in installing such a wire it will be fairly obvious to anyone who looks under the dash or your seat. One would just have to look under the dash and see the wire that does not look like its factory and follow. Then even if its "hidden" it needs to be a place you an reach your hand which means when the car does not start I bet it could be found in 10-15 seconds by running your hand or looking under things. there is only one reason to have a switch hidden.

their are fairly creative things you can do, PM me if you want some of my thoughts.

Saw an video about alarm shops using multiple actions, relay logic using the events to allow car to start. Like turning on parking lights, then left turn signal, ignition switch to run, turn off lights and signal, then start car. It sounded interesting and would be remotely located, so hard to find.

That sounds awesome, but it's a bit time consuming, and I would always worry about failure. Our cars are complicated enough with all the electronics...I just have to remember that "Murphy's Law" applies to me quite a bit.

In an emergency, I want to be able to get in and go.

I did put a hidden kill switch in my old 1992 Jeep Wrangler - I had the top off so much that I wanted to make it as difficult as possible for someone to steal. I figured anything that made a thief have to rummage around looking for the switch was better than nothing.

I don't worry about it on my Focus because of the RFID chip in the key...it makes it a low-theft vehicle.

That does sound crazy awesome. Maybe a bit out of my scope of abilities for one of my first mods, but something that I actually had in mind before. I've seen plenty of arduino/PCB powered keypad devices that did something similar, albeit without the complicated relay setups.
